Abstract
An air fan capable of increasing the amount of air fed in a radial direction thereof. An impeller which includes a plurality of blades for sucking air from one side in an axial direction of a revolving shaft of a motor and guiding sucked air mainly toward the other side in the axial direction is mounted on a rotor of the motor. A casing includes a peripheral wall arranged so as to define a cavity therein in which the motor and impeller are received. A cavity is closed at each of both ends in the axial direction with a closing wall. The peripheral wall is provided at a portion thereof in proximity to an end thereof on the one side with a lateral suction port which permits air to be suckedly introduced therethrough into the cavity in a radial direction of the revolving shaft. Also, the peripheral wall of the casing is provided at a portion thereof in proximity to an end thereof on the other side with a lateral discharge port which permits air suckedly introduced into the cavity to be discharged therethrough in the radial direction. The lateral suction port and lateral discharge port are arranged so as not to be aligned with each other in the axial direction.
